Travel to someplace where there is snow. Ice ages take tens of thousands of years to spread over large areas. Tens of thousands of years from when they start.
If we were not artificially warming the Earth by adding CO2, evidence suggests that we would currently be heading towards an ice age. However, even if we somehow restore CO2 to preindustrial levels in the next few years or whatever, don't expect to see an ice age in your lifetime. Just move to northern Canada or something...
We are heading towards the peak of another warm period. This one will be a little different since man is adding to the heat up. It will not really head back to the cooler period for another 200 years or so.
It can be minimized if following things could be done.
1:Afforestation
2:Controlling rapid population
3:Proper use of fossil fuels
4:Increasing education about population matters
5:Minimize use of CFC and NH3
Guaranteed, if they've gone up. Yet consider an ice plus water bath that you put on a burner, given that it is stirred constantly. Although you could heat the crap out of it, the temperature of the water will not change until all the ice is melted. Now consider how you could supercool the ice water bath to start the model ice age, given the bath is constantly stirred. I don't know either.
Probably yes, there are so many factors involved in climate that nobody can predict what is going to happen, look at the Jet Stream it was only discovered a few decades ago, but has an enormous effect on weather and nobody knows what it was doing in the past.
They have for at least the last ten years. Tube away.

Interglacial periods are around twelve thousand years long. It's been about that long now. I'm a snow tubing enthusiast.
